The morning after the speaker of the lower house of Congress triggered the impeachment process against Rousseff on grounds that she illegally manipulated government accounts, her Workers' Party sprang into action.
The leftist party's strong stand, coming after a defiant and angry statement from Rousseff late yesterday, signaled the start of a political fight that experts say will paralyze a country already suffering from a deepening recession and a spiraling corruption scandal centered on state oil giant Petrobras.
Paulo Pimenta, a Workers' Party deputy, told AFP complaints were being filed that Speaker Eduardo Cunha is using the impeachment drive as an attempt to save his own career after being accused of corruption.
"We are studying a series of measures that aim to block the process," Pimenta said.
The Supreme Court appeal will charge Cunha with "abuse of power and using the legislative power structure to defend himself."
As speaker, Cunha alone has authority to accept or turn down petitions for the president's impeachment and late yesterday he accepted one filed by several lawyers alleging that Rousseff used illegal methods to mask holes in the government budget.
Analysts say the whole impeachment process -- if it passes the many legal hurdles along the way -- could take as long as six or seven months.
Rousseff said yesterday she is confident she will survive the assault and her allies told O Globo newspaper that they have enough votes to block an impeachment vote.
"I have not committed one illegal act," Rousseff said on national television late yesterday.
